All-weak tables are not being revisited after being visited during
propagation; if it gets a new metatable after that, the new metatable
may not be marked.
New release number, updated copyright year2025-05-21T16:52:56+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-05-21T16:52:56+00:00urn:sha1:6e22fedb74cf0c9b6656e9fce8b7331db847c605Bug: check for constructor overflow in [exp] fields2025-05-20T20:55:08+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-05-20T20:55:08+00:00urn:sha1:267ef461d0b13aa28d667f12d1a61452c9db529c
The check for constructor overflow was considering only fields with
explicit names, ignoring fields with syntax '[exp]=exp'.
Bug: Bad error message with fields of string _ENV2025-05-15T18:14:56+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-05-15T18:14:56+00:00urn:sha1:d1ee2a4deb06a335b9ff99530917b828a7ebe3e5
Errors with fields of the string _ENV (e.g., ("_ENV").u + 1) report
the error as comming from a global.
Bug: message handler can be overwritten2025-03-17T19:14:17+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-03-17T19:14:17+00:00urn:sha1:3fe7be956f23385aa1950dc31e2f25127ccfc0ea
A __close metamethod can overwrite a message handler in the stack
when closing a thread or a state.
Bug: Use after free in 'luaV_finishset'2025-03-13T18:42:39+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-03-13T18:42:39+00:00urn:sha1:983bc433e6a60cbc4fe3a16f1d4713bacb8e3509
If a metatable is a weak table, its __newindex field could be collected
by an emergency collection while being used in 'luaV_finishset'. (This
bug has similarities with bug 5.3.2-1, fixed in commit a272fa66.)
Bug: 'luaD_seterrorobj' should not raise errors2025-03-12T19:01:03+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-03-12T19:01:03+00:00urn:sha1:25da574fcbb68bf507431a6091ab73ac434c9428
This function can be called unprotected, so it should not raise any
kind of errors. (It could raise a memory-allocation error when creating
a message).
Bug: Missing error status in panic function2025-01-16T19:25:11+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-01-16T19:25:11+00:00urn:sha1:f5e55be2a0ce64066c1b0554675633b92c91fafb
'luaD_throw' may call 'luaE_resetthread', which returns an error code
but clears 'L->status'; so, 'luaD_throw' should set that status again.
